In the world of racing and performance, BIGGER is always better. Ford Racing gets it - and that‚€ôs why it offers BOSS small blocks in Big Bore versions. The Ford Racing BOSS blocks are designed to be a replacement for the legendary BOSS 302 and BOSS 351 blocks using the latest technology and manufacturing techniques available. Cast from diesel grade iron with siamese bores, thick cylinder walls and decks, BOSS block strength is far superior to any Ford production block ever offered.

Ford Racing Big Bore 351 blocks make it simpler and more economical to build really BIG small blocks. To insure the most precise bore location, concentricity and integrity, the BOSS Big Bore blocks are machined an additional .125‚€Ě during the initial block fixturing and boring stage. With an unfinished bore size of 4.120‚€Ě, Ford Racing BOSS 351 Big Bore blocks make really BIG small blocks.

The Ford Racing BOSS block capability has been proven around the world ‚€ď both on the track and on the street. And, all Ford Racing BOSS blocks are cast and machined to the highest industry standards in the USA.

Same as M-6010-BOSS35192 except allows for bigger bore by deleting coolant crossover holes between cylinders
